A comb jelly. The evolutionary history of the comb jelly has revealed surprising clues about Earth’s first animal.
Why do humans only eat herbivores?
And human beings are the animals on the earth standing at the top of the food chain, so it is normal to eat the meat of other animals. But have you discovered that, in fact, humans rarely eat carnivores and most of them eat herbivores. These are herbivores, because herbivores are docile and easier to tame.

What is the first thing on earth?
Some scientists estimate that ‘life’ began on our planet as early as four billion years ago. And the first living things were simple, single-celled, micro-organisms called prokaryotes (they lacked a cell membrane and a cell nucleus).
What was the smartest dinosaur?
Troodon
Troodon had a large brain for its relatively small size and was probably among the smartest dinosaurs. Its brain is proportionally larger than those found in living reptiles, so the animal may have been as intelligent as modern birds, which are more similar in brain size.
When did the last dinosaur die?
about 65 million years ago
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
